15050689 divided by 20 
The aim is to understand the frequency of 20 in 15050689.

Going ahead to step 1:
20 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 20

Advancing to step 2:
15 divided by 20 is 0 with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Append the next digit (0) from the dividend to 15 and continue with: 150 / 20

Going ahead to step 3:
If we divide 150 by 20, we get 7 and a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 140 from 150 and we're left with 10.
Grab the next digit (5) from the dividend, add it to 10, then carry on: 105 / 20

Advancing to step 4:
20 goes into 105 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 75.0
Subtract 100 from 105 to get 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 20

Going ahead to step 5:
20 goes into 50 2 times with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 752.0
Subtracting 40 from 50 leaves us with 10.
Bring next digit (6) of the dividend behind the 10 and repeat the process: 106 / 20

Let's proceed to step 6:
20 can be fit into 106 5 times, resulting in a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 7525.0
The remainder is 6 after subtracting 100 from 106.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 20

On to step 7:
If we divide 68 by 20, we get 3 and a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 75253.0
If we subtract 60 from 68, we get 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 20

On to step 8:
The number 20 fits into 89 4 times, leaving a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 752534.0
If we subtract 80 from 89, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 9:
The number 20 fits into 90 4 times, leaving a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 752534.4
If we subtract 80 from 90, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
If we divide 100 by 20, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 752534.45
The remainder is 0 after subtracting 100 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
If we divide 0 by 20, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 752534.45
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 12:
0 divided by 20 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 752534.45
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 752534.45 with a remaining 0.0.
